Explanation:
The central nervous system processes stimuli information the body receives, and the peripheral nervous system senses stimuli and carries out the reaction.
Answer:
Let the interbred alleles be represente dy the letters A and B for two genes. Gene A will exist in two alleles, that will icnlude A and g while Gene B exists in two alleles, B and r.
The uppercase alleles are dominant to the lowercase alleles. The interbred long-shaped squash is AABB (aabb) and the true-breeding disk-shaped is ggrr AABB.The F1 offspring are AaBb.
The outcome of interbred of the F1 plants and genotypes and phenotype sof F2 for:
1) the disk-shaped phenotype, an offspring must inherit at least one dominant allele from both genes.
1 ggrr+ 2 Agrr+ 2 ggrB+ 4 AgBr = 9 disk-shaped offspring
2) To get the round phenotype, an offspring must inherit at least one dominant allele for one of the two genes but must be homozygous recessive for only one of the two genes.
1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB = 6 round-shaped offspring
3) To get the long phenotype, an offspring must inherit all recessive alleles:
1 AABB= 1 long-shaped offspring
Hence, the phenotype and genotype of F2 is is 9 disk-shaped offspring and 1 ggrr+ 2 Agrr+ 2 ggrB+ 4 AgBr; 6 round-shaped offspring and 1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB; and 1 long-shaped offspring and 1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB respectively.
Answer:
BC = 4
Explanation:
just look at the values given and you should be able to figure out how the overlap and then find the values left over.
Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
B
Keep in mind that total energy in the beginning and after work remains the same according o thermodynamics theory that energy can't be created or destroyed.
Explanation:
Conversion of energy from one form to another is not 100% efficient. Even the transfer of energy from one object to another (work) is not 100% efficient. This also applies to cells. The inefficiencies are lost as heat energy. Examples of such work in the cells include active transport by cell membrane protein channels, metabolic pathways, and etcetera. Some energy in the hydrolysis of ATP to power these biochemical activities is lost as heat which is part of the reason we remain warm. This energy ends up being lost into the environment as heat (e.g even from sweating).
